3 ciated tapered seats 8. These bosses project slightly out of the plane of the side walls of the spokes and are adapted to receive centrally therein stud members 10 disposed centrally thereof and projecting outwardly of the boss surface as indicated at the left-hand side of Figure 1.

Two tire-receiving rims l2 are provided, these rims each having a gutter or bevel edge [3 and a lateral face I4 for a purpose to be described hereinafter.

In order to mount the rims l2 upon the wheel body 5 there is provided a plurality of wheel mounting lug members indicated generally at l5 which are provided with; laterally spaced, grooved recesses l6 as shown in Figure 2, these recesses conforming generally to the shape of V gutter edge I3 and terminating at their-inner portions in vertically extending rib H, the ribs I! being spaced apart a distance equal to the spacing desired between'the tire rims. The lugs 15 are provided with depending tongue portions or end flanges l8 which are apertured as indicated at [9 and are provided with a ehamfered recess 20 adjacent the outer ends of the openings IS, the chamfered recess 2!] being adapted to receive the chamfered portion 22 of the locking nuts 23 threaded upon the studs It. It will be termediate the seats 8 prevent the inboard'rim moving beyond the desired position; f Two' or.

possibly three sets of lugs are then placed in position and initially drawn up. The outboard rirnis then'hung over the'selug'sJcentering on the land 32, and the remaining lugsare applied over thestuds It,- the under surface of the lugs resting on the seats 8 across the entire transverse As the nuts 23 are tightened,

extent thereof. the lugs l5are moved circumferentiallyand also radiallyo'utwardlydue tot-he angularity of the seats 8, thus exerting a radial expanding force on the rims to chord the rims intermediate the spoke ends and at the same time to provide a positive seating engagementof the gutteredges of the rims within the recesses I6;

The construction is so designed thatjthe lugs l5'- when wedged into final position have the tongue portions I8 thereof 'seated'against the surface of the bosses 9, thereby-providing a positive stopand insuring that the "lug has been driven up into its finalposition; Also; by reason of the chamfered seating engagement of the nut 23in the recess 2!! it will be apparent that the lugs are centered definitely with respect to the studs I0 s o that the ribs I! whichdefine the spacing between the rims will be-positively positioned with respect toa vertical plane through the wheel spider to provide positive parallel alinement of the rims in planes at rightangles to the axis ofrotation. Q I V J With this arrangement it is believed that a positive locking-of the rims upon the spoke ends is provided with a minimumamount of machining required in t he wheel body and with the assurance that the lugs willtransmit the load from the rims directly to the spoke ends through the seats 8. Also, there will be no tipping or rocking of the lugs due to the abutment of the tongues IS with the bosses 9 and the fact that the lugs are in seating engagement on the surfaces 8 throughout the entire transverse extent of such seatin surfaces. Consequently, the lugs will be fixed in position when the nuts 23 are finally clamped tight to provide ior maintaining the rims in positive alinement and in concentric position relative to the axis of the Wheel spider.

It is, therefore, believed apparent that I have provided a novel type of dual wheel assembly, departing entirely from the customary type of such assembly heretofore noted, and I therefore do not intend to be limited except as defined by the scope and spirit of the appended claims.

- I claim: i

l.-In a dual wheel assembly, a wheel spider having radially extending spokes provided at their ends with oppositely sloping seating surfaces extending in a circumferential direction, rim-receiving lugs adapted to seat on each surface at each spoke end, said lugs having transversely spaced rim-receiving'recesses for receiving the 5" bevel edges of opposed inboard and outboard tire rims, and radial shoulders defining the inner axial portions of 'saidrecesses to provide predetermined axial spacing of said'rims on said lugs.

2. In a dual wheel assembly, a wheel spider endswith' circumferentially directed oppositely sloping seats,'stud means extending circumferentially outwardly from saidspoke ends radially I inwardly of and parallelto's'aid seats, lugs hav- 3'5 ing seating portions 'slidable' on said seats and depending'tongue' portions apertured'to move over'said studs, and clamping nuts cooperating tain sai'drims in predetermined axially spaced position'on said spider; s {Bi-In combination, afwheel spider having ra 3 daily extendin hollow spokes provided with solid ends arrangedito provide circumferentially directed oppositely sloping seats, tapered lugs adapted to be clamped on said seats; and axially spaced rim-receiving recesses in' the outer surfaces of said lugs for receiving 'the'bevel'edges of inboard and rims are chorded radially on said spider and are maintained in predetermined axially spaced rela'-' tion.

'4. Thecombination of claim 3 including clamping means for 'centering said lugs on said seats 'in' a common vertical plane normal to the axis of said spider.

5. The combination of claim 3 wherein said.

lugs move radially outwardly along said seats into clamped position to provide for chording of said rims intermediate said spoke ends.

6. The combinationof claim 3-including' circumferentially directed axially spaced radial shoulders on said lugs forming axial abutments for the adjacent lateral edges of said rims.

7. In combination, a wheel spider'having' 'radially extending hollow spokes provided with solid spoke ends, each spoke endhaving formed thereon circumferentially directed; oppositely sloping seats extending transversely thereacross, circumferentially directed studs arranged in a common vertical plane radially inwardly of and parallel to said seats; lugs engaging on said seats for the full width thereof and having depending having radially extending spokes provided at their outboard tire rims, whereby said portions centered over said studs, circumferentially directed recesses in said lugs adjacent opposite ides thereof adapted to receive the annular bevel edges of opposed inboard and outboard tire rims, and clamping nuts engaging said studs to move said lugs over said seats to provide radial outward clamping pressure on said rims at said spoke ends. a

8. The combination of claim-7 including circumferentially extending axially spaced radial shoulders on said lugs providing abutments for predetermining the axial spacing of said rims thereon.

9. The combination, with a spoke end of a wheel spider having radially extending hollow spokes, said spoke end having oppositely directed seats extending circumferentially and radially inwardly from the transverse center of said spoke end, of lugs having seating engagement on said seats for the full transverse width thereof and having a normally depending centrally apertured flange, studs extending parallel to said seats radially inwardly thereof and projecting through said flange aperture, axially spaced rim-receiving recesses in said lugs for mounting the gutter edges of axially spaced tire rims therein, and clamp means engaging said studs for clamping said lugs in fixed position on said spoke end.

10. In combination, a wheel spider having spoke ends provided with circumferentially directed oppositely slopingv seats, lugs for each of said seats, means on said lugs for supporting the annular bevel edges of a pair of tire rims thereon, and means for clamping said lugs on said spoke ends.

11. The combination of claim 10 wherein said rim supporting means includes mean providing for predetermined axial spacing of said rims on said lugs.

12. The combination of claim 10 wherein said clamping means includes mean for alining all of said lugs with reference to a vertical plane through said spider.

13. The combination of .claim 10 including radially extending circumferential shoulders on said lugs forming axial abutment for predetermining the axial spacing of said rims.

14. In combination, a wheel spider having spoke ends provided with circumferentially directed oppositely sloping planar seats, lug means engageable with each seat having arcuate annular recesses adjacent the transverse sides thereof fOr receiving the bevel edges of a pair of tire rims, and clamping means associated with said spoke ends for moving said lugs toward each other on said seats whereby said recesses are moved radially to expand the effective diameter thereof for positively clamping said rims thereon.
